sweeten e,

To all whom it may concern:

Be it known that l, GEORGE G. SEYMOUR,

a citizen of the United. States, residing at Troy county of ltensseloer, snci State of New York, have invented certain new and I lni novementi-i in Valves for Fiushin i hich the following is a speoi relates to such i1nproveof the novel cons uction and coinhini-ttion of parts hereinafter de .l snhseqnei'itiy claimed.

er' -msy he had to the cccoinpan nw s, and the reference characters specification.

' f or characters refer to similar ports in eral figures therein. wire 1 1* e hori same taken on the 1).- il? 3 i is a vertical section taken on th Fig' e broken line 5-5 in Fig. 3. Fig. a. oross-section taken on the broken iine 6--4;- in Fig. 3. Fig. 7 is a. plan view of one end of the fiostnrm. 8 is an edge view. 0' some. Fig. 9 is s. p an View of the upper the valve-operating lever.

'ihe rinoipn-l object of the invention is to increase the durability and eiliciency of valves, particularly those adapted for use in connection with flushing tanks to control the iniet thereto.

.i'lthcr objects of the invention will appear connection with the following description: Referring to the drawings wherein the invenion i shown is preferred form, 1, reposents a. valverplug oi frusto-conicol form eptcrl to fit a similarly formed seat in shell, :2, shown mounted upon a pipe ing, 3, adopted to have connected ith a water pipe 4-. The shell, 2, has,

W, its frusto-conical seat a cylindriciil,

pen-ling spider-formed stem, 6, on the valveping', which plugfalso has an upwz'trrl stcm- ..-ns on "3', adapted toviit endreciprcoetc my, 8, theeuperposed cap or dome, 9, which has its lower end screwed I mounted upon the coupling, 3, by meztnsioi the posts 11. The shdeways,

irked thereon, which form a part of this i-cnsion, forming a slideweyior a (le-i en --portio1'i of t lever, 12, Whieh are on (l' etrioeilly oppo e sides of the sneli, 2,

are connected by the respective links, 15, with the opposite ends of e cross-head, 16, on the upwardly extended valve-stem, 7, whereby, when Sf-LlCl lever is rocked, movements are transmitted to said valve eiong substantially vertical lines. Any known means may be employed for operating the icver i2.

improved valve especially ei lopted for *se in iiushing tanks, and in Fig. i, i have shown it so used, the iever, l2, being conhected with the iii-n1, 17, of s float 18. The men r of connecting the float, 18, with said iever may be varied to adapt the valve for use in tanks of dilierent depths. in a, low shallow tank the arm, 17, of the float is conneoted directly with the upper end. of the lever, l2, cs shown in Fig. 3. When the valve is employed in connection with a deep tank,

i provide an extension, 19, for the vertical erm, 1'7, oi the Frost with the upper end. of semi \SXEGZISIOD as shown in Fig i. I have shown a 'preierred form of non-rotsting connection between the float-arm and said lever in Fi s; 6, 7, 8 and S), one of the connecting mem one being formed with n. lateral project'ion, 20, and the other with a. leterelly opening seat or recess, 21, adapted. to receive said projection, both the projections and the seat being similarly serrated and the members being held together by a screw 22. When the members are hound together by the screw, 22, rotation one member upon the other is rendered impossible. Adjustment is permitted however, by removing the screw, separating the two members and reassembling' them in proper position.

When the excnsion, i9, is employed, the

connection of its lower end with the upper end of: the lever -12, and of its upper end with the arm, L7, oi-the float is accomplished in l the: manner ust descrihcn 111 Fig. 1,! have shown the flushing tank provided with an ordinary hollow lift-vslve,

23, the outlet of the bank, said iift-vsfive Jain? a'dzzpi'u'i "so he operated by the levarZ 05? i1 .shing tanks, it is desirabk to provide fer slight flew Q1 Water 'mrough the outlet pip-e the outlet valva is closead and While the tank is filiing, in order to render certain the proper sealmg of the trap in tbs bowl after the siphonic action Whlch accon'manies Le discharge 01'' the contents of the bowl has been ogezcome. For this purpsse l have prmrided a small pipe, 25, leadmg from the dome, 9, "w a polnt abava the openupper end of 13111 hollo w outlet valve 2 As the tank is filling, the valve, 1, being upan, the inflow of Water is directed into said dome with considerable pressure sufiicien'b in fbrce a, Stream sf Water upwardly thmugh the pipe, 25, from which it is discharged dawn through the baliew 011% let vsfi've, 23, and outiat pipe, 26, t0 the bow "What I claim as new and.

In testimony whereof, I have hexe-lmtn set my hand this 28th day of iS Iarch, 1906.
